A new SIP proxy prototype supporting H.323 protocol in OPNET Modeler

Salma Rattal Abdelmajid Badri Mohammed Moughit

Signaling is one of the keys to voice over IP success; it provides all basic elements to establish successful IP calls with a high-quality service depending on network capacities. To display these competences, OPNET Modeler is an available simulator which evaluates every network environment and tells which scenario is the most suitable. In this developed tool, it is possible to implement voice over IP (Voip) networks with a great management of signaling parameters. However, in OPNET Modeler, there is no model node which offers the possibility to operate networks that support two different signaling protocols (session initiation protocol "SIP" and H.323) in the same time. In this paper a deep study of signaling protocols is conducted together with modifications made to create a new device encompassing proxy to support SIP and gatekeeper to establish H.323 calls in the same scenario.

Directive Beam-Steering Patch Antenna Using Adjustable Metamaterial Superstrate

Lecture notes in electrical engineering (2016)

Hayat Errifi Abdennaceur Baghdad Abdelmajid Badri Aïcha Sahel

Beam-steering antenna is the ideal solution for a variety of system applications, it is most commonly achieved through using phased array, where phase shifters are used to control the relative of the main-beam. However this technique cannot be used in the mobile terminals which use only single radiation element. In this work we present a high directivity and beam steering antenna using simple printed patch covered by adjustable left handed metamaterial superstrate. The design and simulations are carried out using HFSS software. The adjustable metamaterial is based on double omega shaped unit cell. The antenna used is a probe feed rectangular microstrip patch which operates at X band. An appropriate loading of the metamaterial unit cell, through the use of a varactor diodes, enables to vary the medium index of the superstrate within an interesting range, therefore ± 30° deflection of the antenna beam is obtained. Furthermore, using metamaterial superstrate, the antenna performance has been improved significantly, indicating that the directivity can achieve 11.31 dBi and the HPBW is about 23° for all beam-steering angles.

Group student profiling in massive open online courses using educational data mining

International Journal of Data Science (2022)

Abdelghani Hmich Abdelmajid Badri Aïcha Sahel

Student profiling is one of the great accomplishments in the field of educational data mining (EDM). Student profile can mainly offer the most exact description of students in order to be able to offer students the most appropriate personalisation and recommendation. In this paper, we use a demarche for discovering group Massive Open Online Course (MOOC) student profile in relation to their quiz performance. This demarche is based on the combination of hierarchical density-based spatial clustering of applications with noise (HDBSCAN) and apriori algorithm, first the groups of students with similar learning characteristic are extracted by using the clustering algorithm HDBSCAN, then the extracted groups were analysed by using apriori algorithm in order to characterise the distinct profiles of group of students using data collected from a MOOC in Moodle platform. The results show that there are three groups of students organised by quiz performance and learning behaviours. First group is characterised by the low quiz performance, the second group is characterised by the good quiz performance and the third group is characterised by the excellent quiz performance.

CPW Fed Wide to Dual Band Frequency Reconfigurable Antenna for 5G Applications

Abir Zaidi Abdennaceur Baghdad Wahaj Abbas Awan Halima Halima Abdelhakim Ballouk

This paper contains a Co-Planar waveguide (CPW) fed wideband to dual band frequency reconfigurable patch antenna for 5G applications. The frequency reconfigurability is achieved using two variable resistors, which vary the voltage level and hence disturb the current charge distribution. Antenna is designed on ROGERS RO3003 substrate using High Frequency Structure Simulator (HFSS) and compared with CST results. The proposed antenna shows promising results which are shown by comparing with similar works for proposed 5G frequencies.

Trajectory Management of Mobile VoIP over WiMAX

International Journal of Computer Applications (2019)

Salma Rattal Abdelmajid Badri Mohammed Moughit

In order to optimize and make network resources more useful, many studies are conducted.However, WiMAX technology researches don't take enough consideration regarding mobility user management.This paper tackles mobility management of VoIP users over WiMaX.In another way, we propose a new idea to decide the best location of base stations in an enterprise domain according to a daily approximate trajectory of VoIP users.Our research is than organized as follows:Firstly, we watch the users' trajectories on a daily basis then we consider an approximation of users' trajectories.Secondly, this fictive trajectory is subdivided into small segments.The perpendicular bisectors of the latter segments are used to give a cloud of intersecting points.The same procedure is applied to the obtained cloud until we find a set of points where distances between these points are small enough to be considered as negligible.Finally, the base station location will be where the points are concentrated.
